Abstract
A switch for switching fixed size ATM cells and variable length packets of a network. The switch includes an input port mechanism having a plurality of input ports each able to receive cells and packets from the network. The switch includes an output port mechanism having a plurality of output ports each able to send cells and packets to the network. The switch includes a switching fabric connected to the input port mechanism and the output port mechanism for switching either packets or cells from any input port to any output port. The switch includes a mechanism for converting packets to cells when the input port is a packet port and the output port is a cell port and cells to packets when the input port is a cell port and the output port is a packet port, respectively, or not converting cells or packets when the input port and the output port are both cell ports or both packet ports, respectively. The converting mechanism is connected to the output port mechanism and the switching fabric. A communications system. A method for transferring fixed size ATM cells and variable size packets in a network.
